VALVE FOR` REGENERATIVE FURNACES.

Application filed November 12.

To a/ZZ whom it may concern.'

Be it known that I, GEORGE W. VANDER- suon, a citizen of the United States, and a resident of Coatesville, Pennsylvania, have invented certain Improvements in Valves for Regenerative Furnaces, of which the following is a specification.

My invention relates to certain improvements in reversing-valves for regenerative furnaces, the object of the invention being to so construct valves of this type that they will not be rapidly burned out.

A further object is to provide a construetion 'which can be quickly dismantled or reversed and which has independent Watercooled rings for the upper and lower valveseats, said seats being so formed that they In the accompanying drawings, Figure 1 is a sectional view of suiicient oli the Iues of a furnace to illustrate my invention. Fig. 2

for the valve. Fig. 3 is an enlarged view showing one of the joints, and Figs. 4, 5, and 6 are views of modifications.

A is the brickwork of the furnace, having a central stack-flue B, with branches vB B2, each communicating with a valve-chamber D. Each chamber has an extension or hood D', one hood communicating with the furnace-flue C and the other extension communicatin(r with the furnace-flue C. Mounted above tie valve-chambers is thegas-box E, which communicates with the gas-main and the u per ends cf the valve-chambers.

The valve-chambers are constructed as follows: I I are two rings forming the u per and lower ends of the valve-chamber D. ach ring also forms a seat for the valve H, which is hung from a stem I-I, operated in any suitable manner. The rings are reversible, so that when one seat is worn the ring can be turned to provide a new seat. Each ring has a flange, and on the casing of the valvechamber is a flane or lug. Securing-bolts are passed throug the flange on the rings and on the casing, as shown in Figs. 1 and 3, or lon bolts may be used, as shown in Fig. 4, exten ing from one rin to the other. The casing may be lined wit fire-brick K, if desired, as clearly shown in the drawings.

The two rings I I each have an annular water-passage 'L' which is connected to a suitable water-suppl so that the rings are kefpt comparatively cool, and thus the seats or Specification of Letters Patent.

the valve are prevented to a certain extent from burning out. It will be noticed in the drawings that the valve-seats ofthe rings are comparatively sharp and the contact-surface of the valve is segmental, so that when the valve is closed upon the seat it will tend to seat itself correctly, and the comparatively sharp edges of the seat will biteinto any tar or other sediment that is formed on the valve, thus making a tight joint.

While I have shown the valve ofthe peculiar form illustrated, it may be in the form of a globe, as shown in Fig. 4, or of the form in which the bearing-surface is on an an le instead of on a curve, as illustrated in ig. 5. I have made the valves and water-cooled seats as shown so that each can be easily machined on the contact-surfaces in order to make a gas-tight t. The valve may be made hollow, as shown, or in any other manner to secure the necessary strength without water-coolin as I prefer that the valve shall be'sulicient y heated to prevent tar adhering to it and to melt any lumps of tar that may collect on the cooled surface of the seats, or-the valve may be made with the sharp edge and the seat with the beveled or segmental surface, as shown in Fig. 6.

While my invention is especially adapted for reversing gas-valves for use in connection with regenerative furnaces, a single valve may be used for other purposes without departing Jrom my invention.

I claim as my invention- 1. The combination in a gas-valve for regenerative furnaces, of a casing having upper and lower independent rings, each ring being hollow for the admission of water, a casing, and a re-brick lining between the 'two ringls, and means for securing the rings and t e body of the casing together, with a valve, a valve-stem, the valve being open to the chests so that it will become heated and prevent the accumulation of tar on its bearingsurfaces, substantially as described.

2. The combination '1n a gas-valve for regenerative urnaces, of a casing having upper and lower rings, with a valve, a valve-stem, the valve being open to the chest so that it will become heated and prevent the accumulation of tar on its bearing-surfaces, substantially as described.
